单束纤维拉伸法是以简单的单束纤维聚合物基复合材料结构为研究对象,研究固化工艺过程中树脂体积变化与纤维上残余应力之间的关系.同时固化过程中树脂体积是随工艺温度变化而产生变化的,经理论分析及计算得到了固化工艺温度历程对纤维上固化残余应力的影响规律.
A-bunch-of-fiber-tensed is a new method to study the relation between the volume change of resin matrix and the development of cure-induced fiber residual stresses. The subject investigated of this method is not ac-tual parts, but simple a-bunch-of-fiber/resin composites structure. Because the resin matrix appears shrinkage or ex-pansion when the cure temperature varies following the development of cure temperature, it can obtain the effect of cure cycle on cure-induced fiber stresses in composites by calculating and analyzing.
